So let me understand this: the analogous concept to a “victim buffer” in 
the disk drive case (assuming the analogy makes sense at all), would be 
something “glued directly” to the OS filesystem cache? That is, it would 
be on the main RAM side, not on the drive side? In order for the analogy 
to be truly analogous?

Just trying to get things clear here. Because, you know, some people like 
to muddy the waters to distract from the fact that they don’t actually 
understand what’s going on.
